DescriptionThe AZM170 Series is designed for machines/work cellswhere access to a hazardous work area must be controlleduntil safe conditions exist. Their solenoid-latching featurepermits locking a machine guard until dangerous conditions,which may exist immediately after removal of power, haveabated. Solenoid-latching may be controlled by a time delay,motion detector, position sensor or other suitable component.

The unit features independent actuator key (guard) positionand solenoid-latching pin position contacts. These permit theprevention of machine restart until the guard is closed andthe solenoid-latching pin is in the locked position.

The AZM170 consists of an electromechanical safety interlockswitch joined to a solenoid-latching mechanism. Both thesafety switch and solenoid mechanism feature “positive-break”contacts. In addition the actuator key features a built-in latch(unlocked key holding force of 7 pounds), and an auxiliarymanual unlocking device … the latter provided to aid ininstallation and for use in the event of a power failure (whenusing the “unlocking by solenoid” model).

Each unit is supplied with a cord grip and a cap to seal theunused key entry port in the solenoid-latching mechanism.

Typical ApplicationsThe AZM170 is intended for use as a safety interlock switchon movable machine guards which must not be opened untildangerous conditions, which may exist after the removal ofpower, have abated. Such conditions are flywheel overrun,spindle momentum, unstable rest positions, etc. Typicalapplications are textile machines, stamping presses,articulating robot arms, mixing machines, metal workingequipment, printing presses and packaging machinery.

Features & Benefits• Compact design … only 11⁄4" × 3" × 41⁄4". Ideal where spaceis limited.

• Watertight design … meets IP67 washdown requirements.• Highly tamper-resistant … difficult to defeat with simpletools, tape, bent wires, etc. Reduces liability exposure.

• “Positive-break” NC contacts … assure interruption ofsafety circuit upon actuator key removal.

• Two key entry locations … provide mounting flexibility.• Rugged, corrosion-resistant, high-impact glass-fibrereinforced housing … tolerates the most hostileenvironments.

• High-strength stainless steel actuator key … tolerant tomechanical abuse without damage.

• Several styles of actuator key … accommodate a widevariety of movable guards.

• “Power-on” or “Power-off” latching option … forapplication versatility.

• Built-in manual unlatching release (via specialtriangular key) … for easier installation.

• “Padlockable” key … for added security duringmaintenance.

• Designed to meet Performance Level requirementsof EN ISO 13849-1 and Safety Control Categories ofEN 954-1.

AZM161 Solenoid-Latching Safety Interlock Switch

DescriptionThe AZM161 Series is designed for machines/work cellswhere access to a hazardous work area must be controlleduntil safe conditions exist. Their solenoid-latching featurepermits locking a machine guard until dangerous conditions,which may exist immediately after removal of power, haveabated. Solenoid-latching may be controlled by a time delay,motion detector, position sensor or other suitable component.

The unit features independent actuator key (guard) positionand solenoid-latching monitoring contacts. There is a mechan-ical linkage preventing the solenoid position contacts fromchanging unless the key is inserted (guard closed).

The AZM161 consists of an electromechanical safety interlockswitch section with “positive-break” NC contacts and anactuator key. In addition, the solenoid mechanism features 1NO and 2 NC solenoid-latching monitoring contacts, and anauxiliary manual unlocking device … the latter provided to aidin installation and for use in the event of a power failure (whenusing the “unlocking by solenoid” model).

OperationThe AZM161 electromechanical safety interlock switchassembly consists of a rugged switch-solenoid-latchingmechanism and a geometrically-unique locking actuator key.The switch actuating key is typically mounted to a movablemachine guard.

When the guard is closed, the actuating key is held in positionby the solenoid-latching mechanism. The guard may only beopened by energizing or de-energizing (depending uponmodel) the solenoid-latching mechanism.

Upon opening of the guard, the switch’s “positive-break” NCcontacts are forced to open through a direct (non-resilient)mechanical linkage with the actuating key. The NO contactsclose upon key removal.

The machine is prevented from starting until the actuating keyis inserted (guard is closed) and the solenoid has locked it inthe closed position.

Features & Benefits• Solenoid-locking design … controls access to hazardousareas until safe conditions exist.

• Highly tamper-resistant … difficult to defeat with simpletools, tape, bent wires, etc. Reduces liability exposure.

• “Positive-break” NC contacts … assure circuit interruptionupon actuator key removal.

• Conditional “safe” outputs … actuating key must be fullyinserted and solenoid must be actuated to lock key before“closed” safety signal is provided.

• Watertight design … meets IP67 environmentalrequirements.

• High-strength, stainless-steel actuator key … toleratesmechanical abuse without damage.

• Rugged, corrosion-resistant housing … tolerates hostileenvironments.

• Four optional key entry locations … provide installationflexibility.

• Independent actuator key position and locking pinposition monitoring contacts … provide a higher degreeof safety.

• Available in “solenoid-locking” and “solenoid-unlocking” models … for application versatility.

• Designed to meet Performance Level requirementsof EN ISO 13849-1 and Safety Control Categories ofEN 954-1.

• Wide selection of accessories … to meet diverseapplication requirements.

Typical ApplicationsThe AZM161 is intended for use as a safety interlock switchon movable machine guards which must not be opened untildangerous conditions, which may exist after the removal ofpower, have abated. Such conditions are flywheel overrun,spindle momentum, unstable rest positions, etc. Typicalapplications are textile machines, stamping presses,articulating robot arms, mixing machines, metal workingequipment, printing presses and packaging machinery.

Features & Benefits• Solenoid locking design … controls access to hazardousareas until safe conditions exist.

• Non-contact sensing … for long term reliability.• Dual purpose handle … unlatches and opens guard—noadditional door handles are needed.

• Integral LED diagnostics … indicates operating states• Integral self-monitoring and door detection sensors …satisfy requirements of PLe to EN ISO 13849-1 SafetyControl Category 4 to EN 954-1. *See Note Below.

• One-hand emergency release … hazardous area can beleft quickly and safely—even during a power failure.

• Switch and actuator do not protrude into door opening …no risk of injury or damage from a protruding actuator.

• Dual PNP 250 mA safety outputs … for application versatility.• Designed for “daisy chaining”… up to 31 devices, max200 m, can be wired in series without detriment to safetyperformance level.

DescriptionThe AZM 200 Series is designed for machine/work cellswhere access to a hazardous work area must be controlleduntil safe conditions exist. Their solenoid-latching featurepermits locking a machine guard until dangerous conditions,which may exist immediately after removal of power, haveabated. Solenoid-latching may be controlled by a time delay,motion detector, position sensor or other suitable component.

The AZM 200 consists of a solenoid-latching interlock andactuator unit with door handle and optional emergency exithandle. The actuator is always inserted into its housing,protecting the actuator and the operator against damage andinjury. Utilizing pulse-echo sensor technology, the actuatorand interlock can have an offset of ±5 mm and the actuatorstill engages the interlock.

Due to the one-hand operation of the emergency exit handle,the hazardous area can be left quickly and safely—even dur-ing a power failure (when using the “unlock by power” model).

The solenoid interlock is a dual channel design with twoshort-circuit proof, safe PNP outputs, each of which canswitch up to 250 mA.

With continuous internal function tests, the monitoring ofthe safety outputs and the use of door detection sensors,up to 31 AZM 200 solenoid interlocks can be wired in serieswithout detriment to the safety performance level/controlcategory (PLe to EN ISO 13849-1/Control Category 4 toEN 954-1).

Typical ApplicationsThe AZM 200 is intended for use as a safety interlock switchon movable machine guards which must not be opened untildangerous conditions, which may exist after the removal ofpower, have abated. Such conditions are flywheel overrun,spindle momentum, unstable rest positions, etc. Typicalapplications are textile machines, stamping machines,metal working equipment, printing presses and

packaging machines.

Features & Benefits• Magnetic-latching design … controls access to hazardousareas until safe conditions exist (100 lbs. locked holdingforce).

• Forced-closed operating principle … no mechanical weardue to non-contact design.

• Integral LED diagnostics … indicates operating states• Integral self-monitoring and door detection sensors …satisfy requirements of PLe per EN ISO 13849-1, ControlCategory 4 per EN 954-1. *See Note Below.

• Designed for “daisy chaining”… up to 31 devices, max200 m, can be wired in series without detriment to safetyperformance level.

• Automatic magnetic latch (35 N) … no mechanicallatching required (“r” version only).

• Smooth surfaces allow for easy cleaning … ideal wherehigh hygienic standards need to be maintained.

• Dual PNP 250 mA safety outputs … for application versatility.

DescriptionThe MZM 100 Series is designed for machine/work cellswhere access to a hazardous work area must be controlleduntil safe conditions exist. Their magnetic-latching featurepermits locking a machine guard until dangerous conditions,which may exist immediately after removal of power, haveabated.

The MZM 100 consists of a magnetic-latching interlock andactuator unit. An electromagnet is utilized to generate a 500 Nholding force. An integrated pulse-echo based sensor detectsand monitors the position of the safety guard. This sensortechnology permits an offset between the actuator and inter-lock of ±5 mm vertical and ±3 mm horizontal.

The MZM100 magnetic-latching interlock is a dual channeldesign with two short-circuit proof, safe PNP outputs, each ofwhich can switch up to 250 mA. The holding force is perma-nently electronically measured and monitored. If the holdingforce drops below 500 N, the safety outputs are not enabled,recognizing a dirty interlock.

With continuous internal function tests, the monitoring ofthe safety outputs and the use of door detection sensors,up to 31 MZM 100 magnetic-latching interlocks can be wiredin series without detriment to the Safety Performance Levelcontrol category (PLe per EN ISO 13849-1/Control Category 4per EN954-1).

Typical ApplicationsThe MZM 100 is intended for use as a safety interlock switchon movable machine guards which must not be opened untildangerous conditions, which may exist after the removal ofpower, have abated. Such conditions are flywheel overrun,spindle momentum, unstable rest positions, etc. Typicalapplications are textile machines, stamping machines,food processing equipment, metal working equipment,wood working and packaging machines.

DescriptionThe TZF/TZM Series is designed for machines/work cellswhere access to a hazardous work area must be controlleduntil safe conditions exist. Their solenoid-latching featurepermits locking a machine guard until dangerous conditions,which may exist immediately after removal of power, haveabated. Solenoid-latching may be controlled by a time delay,motion detector, position sensor or other suitable component.

The unit features independent actuator key (guard) positionand solenoid-latching monitoring contacts. These permit theprevention of machine restart until the guard is closed andthe solenoid-latching pin is in the locked position.

The TZF/TZM Series consists of an electromechanical safetyinterlock switch with “positive-break” contacts and a lockingactuator key. In addition, the TZFS model features an auxiliarymanual unlocking device … the latter provided to aid ininstallation and for use in the event of a power failure (whenusing the “unlocking by solenoid” model).

OperationThe TZF/TZM Series of electromechanical safety interlockswitch assembly consists of a rugged switch, a solenoid-operated latching mechanism, and a geometrically-uniqueactuator key. The switch actuating key is typically mounted toa movable machine guard.

When the guard is closed, the actuating key is held in positionby the latching mechanism. The guard may only be opened byenergizing or de-energizing (depending upon model) thelatching mechanism.

Upon opening of the guard, the switch’s “positive-break” NCcontacts are forced to open through a direct (non-resilient)mechanical linkage with the actuating key. The NO contactsclose upon key removal.

The solenoid-latching mechanism circuit features a NO anda NC contact which permit monitoring its status. This NCcontact is wired in series with the NC contact in the safetyswitch circuit. Thus the machine is prevented from startinguntil the actuating key is inserted (guard is closed) and thesolenoid has locked it in the closed position.

Features & Benefits• Solenoid-locking & spring-locking designs … controlsaccess to hazardous areas until safe conditions exist.

• Highly tamper-resistant … difficult to defeat with simpletools, tape, bent wires, etc. Reduces liability exposure.

• “Positive-break” NC contacts … assure circuit interruptionupon actuator key removal.

• Conditional “safe” outputs … actuating key must be fullyinserted and solenoid must be actuated to lock key before“closed” safety signal is provided.

• Watertight design … meets IP67 environmentalrequirements.

• High-strength, galvanized-steel actuator key … toleratesmechanical abuse without damage.

• Rugged, corrosion-resistant housing … tolerates hostileenvironments.

• Three optional key entry locations … rotatable actuatorhead provides installation versatility.

• Independent actuator key position and locking pinposition monitoring contacts … provide a higher degreeof safety.

• Padlockable key … for added security during equipmentmaintenance.

• Designed to meet Performance Level requirementsof EN ISO 13849-1 and Safety Control Categories ofEN 954-1.

• Wide selection of actuating keys … to meet diverseapplication requirements.

• Special types for food industry … please consult factory.

Typical ApplicationsThe TZF/TZM Series is intended for use as a safety interlockswitch on movable machine guards which must not beopened until dangerous conditions, which may exist after theremoval of power, have abated. Such conditions are flywheeloverrun, spindle momentum, unstable rest positions, etc.Typical applications are textile machines, stamping presses,articulating robot arms, mixing machines, metal workingequipment, printing presses and packaging machinery.

DescriptionThe AZM415 Series is designed for movable machine guardswhere access to a hazardous work area must be controlleduntil safe conditions exist. Their solenoid-latching featurepermits locking a machine guard until dangerous conditions,which may exist immediately after removal of power, haveabated. Solenoid-latching may be controlled by a time-delay,motion detector, position sensor or other suitable component.

Latching may occur upon energizing or de-energizing thesolenoid — depending upon model. In addition the AZM415features “positive-break” NC contacts, and an adjustable-forceball latch which maintains a holding force on the guard whenthe key is in the unlocked state.

A two-key model is also available for guards which may beopen in two directions (Model AZM415-33zpdk).

OperationThe AZM415 two-piece electromechanical safety interlockswitch consists of a rugged switch and solenoid-latchingmechanism and a geometrically-unique actuating key. Theswitch actuating key is typically mounted to a movablemachine guard.

When the guard is closed, the actuator key is locked inposition by a toggle-lever system. The guard may only beopened by energizing or de-energizing (depending uponmodel) the solenoid-latching mechanism.

Upon opening of the guard the switch’s “positive-break” NCcontacts are forced to open through a direct (non-resilient)mechanical linkage with the actuating key. The NO contactsclose upon key removal.
